The aspect ratio of an image is the ratio of its width to its height. It is expressed as two numbers separated by a colon, in the format width:height. Common aspect ratios are 1.85:1 and 2.40:1 in cinematography, 4:3 and 16:9 in television, and 3:2 in still photography
The difference is that whilst D1 has a 4:3 aspect ratio 960H has a 16:9 widescreen aspect ratio. The extra pixels are used to form the increased area to the sides of the D1 image. The pixel density of 960H is identical to standard D1 resolution so it does not give any improvement in image quality, merely a wider aspect ratio.

On CRTs, there was often a difference between the aspect ratio of the computer resolution and the aspect ratio of the display causing non-square ...
In the 1990s, widescreen televisions offered a wider 16:9 aspect ratio (1.78 times the height instead of 1.33) and allowed films with aspect ratios of 1.66:1 and 1.85:1 to fill most or all of the screen, with minimal letterboxing or cropping required. DVD packaging began to use the expression, "16:9 – Enhanced for Widescreen TVs."
Classic television aspect ratio 4:3, and two wider ratios. Widescreen images are displayed within a set of aspect ratios (relationship of image width to height) used in film, television and computer screens. In film, a widescreen film is any film image with a width-to-height aspect ratio greater than 4:3 (1.33:1).
